ALBANY, N.Y. (AP) — The agency responsible for New York City's upstate reservoirs says excavation projects have turned up a trove of fossils and Native American artifacts.

The Department of Environmental Protection says more than 400 items including quartz projectile points, blades and elements of stone tools were found during work on the 153-acre site of the Catskill and Delaware Ultraviolet Light Disinfection Facility in Westchester County. They date back several thousand years to the late Archaic Era and beginning of the Woodland Period and will be given to the historical society that serves Sleepy Hollow and Tarrytown.

Two fossils of the earth's oldest trees were found during reconstruction of the Gilboa Dam in Schoharie County. They date to 380 million years. They'll be loaned to the Time and the Valleys Museum in Grahamsville.
